understand great video helps a lot.

What is the benefit of doing this exactly? Don’t the vehicle run just fine

ignition harness under the column

using a battery isolator, the accessories are running off one battery so
that your starting battery is never affected.

78-DL. The factory battery should be relocated to the passenger side and
the new battery for the driver side should be one top and side posts
